Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual curation by experts is used to build databases, then data accuracy and reliability are improved, but time consumption and productivity are worsened
Solution Approach 1:
The patent introduces an intermediary system (image processing pipeline with CNNs and NLP models) that bridges the gap between raw pathway diagrams and structured database entries. This intermediary automatically extracts entities, relationships, and metadata from diagrams, reducing reliance on manual expert curation while maintaining data quality through multiple processing stages including image preprocessing, object detection, semantic analysis, and conflict resolution mechanisms.
2Device complexity
If graphical information is neglected in favor of text mining, then processing complexity is reduced, but information completeness and measurement precision are worsened
Solution Approach 1:
The patent segments the complex task of diagram analysis into distinct processing stages: image preprocessing, basic object detection (shapes, lines, arrows), text recognition, semantic analysis, and relationship extraction. Each stage handles specific types of graphical information independently, allowing the system to process complex visual data systematically while maintaining information completeness and enabling efficient computation through modular architecture.
Data Source
AI summary
A method for extracting information from a molecular pathway diagram may be provided. The method includes providing a molecular pathway diagram, detecting basic graphical structural elements in the diagram resulting in a set of basic objects, detecting a graphical semantic of each of the basic graphical structural elements resulting in a set of structural primitives, and detecting a graphical syntax of the basic graphical structural element relative to each other and to the diagram. Furthermore, the method includes assigning metadata to a plurality of the detected basic graphical structural elements, where the metadata includes basic graphical structural element data, graphical semantic data and graphical syntax data resulting in a set of entities and relationships.
